Abstract: A computing system for searching for and identifying data repository deficits includes an interactive database of items, a data repository that stores a first type of information related to items, a search engine configured to identify items that do not have an amount of the first type of information that meets a first threshold, a candidate selection interface that provides functionality for the user to select an item from recommended candidate items needing the first type of information, a user interface via which the user can provide the first type of information for an item selected by the user, a game system configured to calculate for a game scores and rankings based at least in part on data stored in the data repository.

Abstract: Tag suggestions enable a hosting entity such as a website to determine one or more tags to suggest to a user for association with a particular item within an electronic catalog. After this determination, the hosting entity may suggest the determined tags to the user. To determine these tags, the hosting entity may employ techniques to determine items related to the particular item. The hosting entity then suggests some or all of the tags associated with the related items. Additionally or alternatively, the hosting entity may determine certain metadata associated with the particular item. The entity then may suggest this metadata, or some related phrase or tag, to the user for association with the particular item. However the tag suggestions are determined, the hosting entity may rank the tag suggestions to determine which tags to present to the user or to determine an order in which to present the tags.

Abstract: Criterion-based feedback allows users to provide useful information in a quick and easy to understand fashion. When information for an item is relayed to a user, the user is provided with the ability to provide feedback for any criteria relating to the item. In some embodiments, this feedback takes the form of a submission of a response to a question or statement pertaining to a criterion for the item. The user is able to create new responses if the existing responses do not adequately convey the feedback that the users wishes to submit. Further, a user can also submit entirely new questions and/or statements, along with corresponding new responses, that correspond to a criterion relating to the item. Such an approach provides flexibility for users to quickly and easily provide feedback on specific criteria that might be useful for other users viewing information for that item.

Abstract: A system includes an interactive item catalog and a data repository that stores purchase histories for users, first reviews for items submitted by users, and first review helpfulness scores. A search engine system identifies catalog items that do not have reviews from users. The system includes a user interface that enables the user to select an item identified by the search engine system as not having user reviews. The systems includes review entry user interface via which the user can enter a first review for an item selected by the user. A game system is configured to calculate for a first review game first review scores and first review rankings for users based at least in part on data stored in the data repository and the first review scores. The system includes an interface configured to provide information to users related to their first review scores and rankings.

Abstract: Relatively ranking items based on subjective attributes of the items, and for discovering these relatively ranked items. A voting server as described may include a voting application that receives an indication of an item of interest to a customer. Based on preferences indicated by customers, the voting application may rank the item and one or more other items for the subjective attribute. The voting application may also send data representing a user interface to a client system, with the user interface including representations of the item and the other item. The user interface may arrange the representations of the items along an axis corresponding to the subjective attribute.
